Properties of Ascaris muscle mitochondria. 1. Cytochromes
Abstract:
1. The cytochrome system in Ascaris muscle mitochondria was further characterized using purer preparations. 2. Difference spectra (at 22 degrees C and -196 degrees C) of the mitochondrial preparations using succinate and ascorbate plus N,N,N' ,N'-tetramethyl-p-phenylenediamine show that Ascaris muscle mitochondria contain cytochromes c1, c and aa3, and also at least three b-type cytochromes. The b-type cytochrome is the predominant component. 3. Cytochrome c and Ascaris cytochrome b-560 can be extracted from the mitochondrial preparations with 150mM KCl, leaving the membrane-bound cytochromes c1, b and aa3 in the KCl residue.

Microscopic Anatomy of Skeletal Muscles
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...
Specialized Characteristics of Cardiac Muscles
Cardiac muscle cells are smaller than skeletal muscles, averaging 10–20 mm in diameter and 50–100 mm in length. However, they have large energy demands for continuous contraction and relaxation. This energy is almost exclusively derived from aerobic metabolism of energy reserves in...
